I'm having a pool party in a few weeks and am looking to pick up some equipment - It's a one time thing, so I'm not looking to pick up anything too extravagant.

If possible, I'd like to augment my existing, somewhat low budget, sound system, and buy something I'll be able to add to my home sound system.

I currently have this low end 500 watt Pyle amp, and a pair of Pioneer SB-BS22-LRs

My thought right now is to pick up a pair of Polk T50 standing speakers (I assume the Pioneer brand has merged with Polk now?) and maybe a PWS10 Subwoofer.

I know it would probably be a crime to most audiophiles to use this stuff for an outdoor party, but again the main purpose here is to get the job done for background music, and do so in a way that will enhance my setup. Killing 2 birds with 1 stone.

The alternative, honestly, is to pick up a really cheap outdoor speaker that I wouldn't use afterwards.

Any help or advice is highly appreciated!
